Usually critical data is stored in DB. We can periodically poll and combine key metrics from DB into a data report, such as how many tables/collections in DB, how many items in each critical table, etc. Data report enables people to visualize the history and trend of key metrics.
Furthermore if the basic data report can be generated automatically, people can easily add more metrics, which may make more business sense. The most exciting part is that we can get a general solution which applies to different projects! So how we can get this idea started?
